 Tonga has crashed twice, once on January 31, again when it was restarted
 on February 16:

 > Feb 16 06:25:01.238 [notice] Tor 0.2.2.22-alpha (git-21b3de6cf37d4e60)
 opening new log file.
 > Feb 16 06:25:01.327 [err] Unable to add own descriptor to directory:
 Skipping router descriptor: not in consensus.
 > Feb 16 06:25:01.327 [warn] options_act(): Bug: Error initializing keys;
 exiting
 > Feb 16 06:25:01.327 [err] set_options(): Bug: Acting on config options
 left us in a broken state. Dying.

 Both crashes were at the same time of day, and with identical log
 messages.  Tonga is now running 0.2.1.29 again as a stopgap measure, but
 we need to find and fix this problem.

 The "Skipping router descriptor: not in consensus." message came from
 [https://gitweb.torproject.org/tor.git/blob/refs/tags/tor-0.2.2.22-alpha:/src/or/routerlist.c#l3313
 src/or/routerlist.c line 3313], in router_add_to_routerlist.  The only
 changes 'git blame' turned up earlier in that function that are present in
 0.2.2.22-alpha and not in 0.2.1.29 were made in
 [https://gitweb.torproject.org/tor.git/commit/9ca311f6220cd52a0f8fcb3bc072cd9569bd1c6e
 9ca311f6 (Allow using regular relays as bridges)].
